T all whom it may concer/n.' 'i

Be it known that I, Osons Znlui,.a sub1ect of the Emperor of Austria-Hunary, residing at Cleveland, in the county o Cuyahoga and State ofOhio,have invented a certain new and useful ImplOvement' in Grease- Cu s, ofwhich the following is. a full, clear, an exact description, referencebeinghad to the accompanying drawings.

- .This invention relates.' to grease cups of cup is enabled to have avery neat appearl they occupy when t the type having a cu member,- acaps crew threaded thereon, an internal mechanism to retard the rotation ofthe'cap 'and any undesired operation thereof.

The object -of the invention is to provide such a grease cup in a formwhich shall be simple and very `economical in' its tion, and be eiicientin service.y To is end I have provided a lcup with an external thread,an internallyA threaded cap screwii on to the cup and having a-allynplagg' non-circular bar which rotates withthefcal, there being alieadrotatably carried by the cup having-a non-circular opening whichsaid bar engages, and a spring causing a periodic frictional locking oft e head to cap as the cup rotates. By this means, the detent mechanismfor the cap is containedentircly within the grease cup, It is therebyprotectedand out -of the way, and the grease ance; 4

The invention is hereinafter Afully exl'plained and its essentialcharacteristics set out in the claims. In the drawings, F igurev 1 is'alongitudinal or axial section of one form of .my grease cup, the partsbeing sh'own in the position 1e cup is practically full yof grease; Fig:2 is a cross section of such cup, indicated by the line 2--2 on'v Fig.1;

Figx is a" plan of. the retaining head and spring; Fig. 4 is a verticalsection of the cup member alone; Fig. 5 is avertical section of amodified'form of cup member and retaining device; Fig. 6 is a plan ofsuch retaining head; Fig. 7 is an edge view of the retainin head of thismodification; Fig. 8 is a vertica section'of :mother modification of.the I.cup member Fig. 9 is a side elevation of the retaining head ofthis member; Fig. 10 is' a topplan of such head; Figs. 11 and 12illustrate a head for mounting in the cup member and having aportionofitself constituting'the roduc-IV ig."12 a vertical sectionlportion 12 (which may be hexagonal, for example as indicated by thevertical lines 18), and ab ternal .screw threads.A A

`The cap 2 is referably a pressed sheet metal member. t has plreferablya cylin- 'ch are internal threads 21. .Near the .upper edge of the wall-the ca has a'knurled portion, as at23, to

provi e a good fin eholdr The-bar. 3 is of any lion-clrcular orm and isshownas a squarev bar.. It is'securel fastenedto the top of the cap,for. examp e, b forming the upp'rpo'rtion'pf this bar wit 'an outwardshoulder 31 and a shank 32, which extends throughgan opening in the top-of the cap and .is riveted over above the-top, as shown in'F1g. 1.

The rotatable head 4, 4, 4b -or 4 in the different embodiments standswithin the cu andhas a non-circular (in thiscase squared) o enin'g41.which the rod 3 occupies, -so that t e head is necessarily turned .as.the cap is screwed on to the cup. l.Suitable openings 42 are madethrough thelhead to allow the passage lofthe grease, as, 4for example,the two shown in Figs. 1 and 3. 'Suitable means, hereinafter to bedescribed, are provided, whereby the head 4, while capable of rotatl ingin the cup, has its rotation restricted periodically and more severelyin'th screw.

ing-oif direction than in thescrewing-on di-vrection. The result o fthis is that .the cap may be easily turned on to the cup to'feed thegrease, but to tum it 'o' 'requires greater force, whereby one does not.inadvertentl turn it ott' when he intends to tum it on, an in turning iton, the periodic restriction ot the rotation indicates the amount it--is turned' and forms a convenient measure ior the feed of the grease.

end 50 of the spring is and to spring into The head 4 in Figs. 1 to 4.;4*? in Figs. 5 to 7; 4b in Figs. 8 to 10; and 4 in 12 is in eachcasemounted within the head of the cup resting on the outward shoulder14 where the cup fiares from the angular portion and heldin place-by theturned-in top flange 15 of the cup wall. The head, in each case, has atop portion 23 which is preferably of an upwardly rounding form and hasa downwardly extending wal `or portion which lies wit-hin the cup. Asstated the head has the angular opening 4l for the bar 3 and one or moregrease openings 42.

so far given ap lies construction' of all of the figures, t e omittedparts of the cap in Figs. 5 and 8 bein lar to that shown in lig.1. Thedi erence inthe various embodiments-shown resides in the spring detentconnection between the head and the cup. I spring detent connection forthe various In the form shown in Figs. 1 to 4, the head 4 is inwardly.flanged at its lower edge, as shown at 45 and above this flange ismounted the spring 5. This spring is a partially circular piece of wirehaving an end 50, which is turned outwardly through an opening 46 in thehead. This projecting adapted to bear against the cup wall as the headis turned, notches 16 formed in that wall, as shown in Fig. 4. Thenotches preferably each have one face gradually inclining and the otherabruptly inclining, the gradually inclined face opposing rotation ofthecap in the screwing on direction and the 'abrupt face opposing rotationin the screwing-off direction, so that the cap,4 which in turning mustturn the head, will rotate more' freely in the screwing-'on directionthan in the screwing-off direction. In the embodiment shown in Figs. 5to 7, the head 4a itself carries a projection 47, pressed upwardly fromthe wall or flanged edge 44 of the head, adapted to coperate with acorresponding depression in the overturned edge 15 of the cup. In thiscase I provide a coiled spring 5F within ,the cup, pressing the headupwardly andbearing at its lower-end. against the internal shoulderprovided where the angular portion j oins the nipple portion of the cup.

In the form shown in Figs. 8 to 10, the head 4'J has at the lower edgeof its wall 44 an outward {iange 45b which provides an annular spacebeneath the inward edge 15 of the cup for the reception of a helicalspring 5". This spring'tends to press the head downwardly so that anotch -or upwardly pressed shoulder 47b in the flange 45b 'cooperatesperiodically with a corresponding shoulder in the cup portion'14.

In the form shown in Figs. 11 and 12, the head 4 is designed to fit intothe cavities Figs. 11 and to the,
